Restore previous session though unchecked always tries to restore previous session on startup. It's annoying!

Posted

Restore previous session though unchecked always tries to restore previous session on startup. It's annoying! That's it in a nutshell. Though the box is unchecked by default, the application still attempts to do a restore which delays my startup of Firefox. How do I get around this? Is there a patch?

Chosen solution

Use one of these to close Firefox if you are currently doing that by clicking the close X on the Firefox title bar.

  • "3-bar" menu button -> Exit (Power button)
  • Windows: File -> Exit
  • Mac: Firefox -> Quit Firefox
  • Linux: File -> Quit

You can check if you have a user.js file in the Firefox profile folder that sets the browser.sessionstore.resume_session_once pref to true.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:preferences page.

Possibly Firefox is not exiting completely (you may need to allow more time) before Windows shuts down. Firefox integrates with a new feature of Windows 10 to restore itself in that situation. It can be turned off, although in that case, Firefox might do a crash recovery on startup. See: Firefox starts automatically when I restart Windows.

Thanks for the comeback but that's not the problem. I've ended my Firefox session, usually, an hour before exiting the OS.

Could you check for a user.js file in your profile folder? This file could contain a "just restore the session this once" command, but since Firefox doesn't delete the file after running it, that will happen at every session. There is a section of this article on how to track down a user.js file: How to fix preferences that won't save.

Also, there's a preference that can help distinguish between a regular restore and a crash recovery.

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk.

(2) In the search box above the list, type or paste sess and pause while the list is filtered

(3) Double-click the browser.sessionstore.max_resumed_crashes preference to display a small dialog and change the value from 1 to 0 (that's a zero) then click OK

After that, when Firefox starts up and believes there was a crash, instead of trying 1 automatic recovery, it will show a screen asking if you want to recover your earlier session.
